**课程名称：** 区块链扩容解决方案 **课程概述：** 该课程旨在帮助学习者理解区块链扩容解决方案，以应对当前区块链技术（尤其是以太坊）在交易吞吐量低和高交易费用方面面临的挑战。随着 DeFi 和 Web3 的快速发展，对可编程区块链的需求日益增长，而以太坊每秒仅 15 笔交易的处理能力远低于 Visa 等支付网络的 1700 笔交易。高昂且不区分交易价值的 Gas 费用，使得小额交易成本过高，严重阻碍了 Web3 技术的广泛应用。 特别是在游戏等需要频繁微交易的 Web3 新兴领域，对能够低成本处理高并发交易并提供与以太坊相媲美安全性的区块链的需求尤为迫切。 因此，各种 Layer-1 和 Layer-2 扩容解决方案应运而生。本课程将深入讲解这些解决方案的不同类型，包括侧链、Plasma 链、Rollups 和 Shard 等，并探讨它们背后使用的多种技术。 **学习建议：** 鉴于课程内容可能较为专业和复杂，建议学习者放慢节奏，逐一理解每个主题后再进入下一个，并务必阅读视频中提供的所有扩展阅读材料。
As per the Chainalysis State of Web3 Report June 2022 Report, cryptocurrencies with the smart contract functionality that powers DeFi and web3 now account for 45% of all blockchain transactions. This means growing demand for programmable blockchains. Ethereum is still leading but there is a multitude of problems with Ethereum. Apart from low throughput at just around 15 transactions per second compared to 1700 transactions per second for the visa network, a high gas fee creates a major bottleneck for Ethereum to drive mass adoption of web3 tech. As the gas fee does not depend on transaction value, smaller transactions are especially expensive on Ethereum as shown by the mentioned report.Now, many emerging fields in web3 such as gaming involve frequent microtransactions creating an urgent need for blockchains that can handle higher transaction throughput at a low cost and offer security comparable to ethereum.This brings us to scaling solutions. Various Layer-1 and Layer-2 scaling solutions are being built to keep pace with the rapidly growing web3 ecosystem. These scaling solutions come in various forms and use a multitude of technologies.Understanding scaling solutions can be challenging because for that we need to understand the fundamental working of blockchains.This course wants to help you understand different types of scaling solutions - from sidechain and plasma chains to rollups and shards.So, let us get started.As these topics can be considerably esoteric….I request you to go slow with the course material and understand one topic at a time before moving to the next one. I have added many reading material links to the videos. Please read all of them.
